Linear Actuator Promises Extended Motor Life, Reliable Operation

Compared to translational leadscrew devices, the company's new linear actuator with ball screw is claimed to reduce friction, thereby extending motor life. The unit's hollow shaft accomodates a variety of leadscrews up to 3/8" in diameter. A threaded front-shaft extension and hub allow for ballscrew attachment to the rotating hollow shaft.
This size 23, single-stack dc stepping motor measures 2.25" x 1.8" and features a peak operating torque of 50 oz/in. The motor can achieve up to 300 lbs. of linear force while providing up to 10" of linear travel per second.
